The acronym âSAP,â for Systems, Applications, and Products in Data Processing, is the name of a corporation that specializes in business products and services designed to improve operational efficiency.
In 1932, Karl Jansky at Bell Labs revealed that stars and other objects in space radiated radio waves. Credit: NRAO/AUI. Radio waves have the longest wavelengths in the electromagnetic spectrum. They range from the length of a football to larger than our planet.Heinrich Hertz proved the existence of radio waves in the late 1880s. He used a spark gap attached to an induction coil and a separate spark gap on a receiving antenna.n 1932, Karl Jansky at Bell Labs revealed that stars and other objects in space radiated radio waves.

A wave is a disturbance that travels through a medium in a periodic fashion, carrying energy without transporting matter. Waves are described and measured by five wave parameters: the period, the frequency, the amplitude, the wavelength, and the speed.The period of a wave is the time it takes to complete one cycle. The frequency is just the opposite; it's the number of wave cycles that are completed in one second.Amplitude and wavelength are both measures of distance. The amplitude measures the height of the crest of the wave from the midline. The wavelength measures the horizontal distance between cycles. wave is a disturbance that travels through a medium in a periodic fashion, carrying energy without transporting matter.
